I vote DouginMB.Rule of thumb is only for initial estimation
i.e to determine the project cost. But it should never be used for selecting the equipment for actual installation.
There are many Heatload software available in the market the best is carrier's E-20 II, which gives you energy analysis...
As per my opinion it is possible to get the lower evaporator
temperature but not because of lowering the condensing temperature. By lowering the condensing temperature to acceptable limit(Refer manufacturer data) you can increase the refrigerating effect(TR).Refer enthalpy-Entropy chart for a...
"Iteration" means trial and error method.
During heatload calculation you will have to assume some fresh air quantity to calculte dehudified CFM requirement.
You will have to reiterate this procedure by varying fresh air quantity till it balances with dehumidified CFM.
Unless this...
I am sorry, Perhaps not agree with all above explanation.
My answer to CHIPFULLER's question is as follows.
I will start with basics. If you refer to carrier handbook or any other engineering book on Air-conditioning. You will find that the grand total heat, in your case it is 8100btu/hr i.e...
Hi,
This is anand here. I am working with Consultancy in INDIA
and responsible for HVAC system design.
Here in INDIA we only do cooling system. But, I am working
on one project where I have to provide heating system for
winter. Can u provide me information on how to calculate
